THEME: none, but the grid looks like a flaming I or a wild X, which reflects the numerous X's in this puzzle
GOOD ONES: Food often served in chains PIZZA [had an image of a waiter in chains]
Rhine whine ACH
BTW: Entrance BEWITCH [I thought doorway]
Sex appeal
HOTNESS [not a word in my lexicon, but HEAT is --- guess it's common useage among the illiterati]
"Since I Don't Have You" is a great doo wop from my teens replete with personification --- wonder how it sounds to today's kids --- pobably too much melody, so it's sappy.
RATING:

Three grins = Loved it; Two grins = Enjoyed it; One grin = A bit bland for my taste; One teardrop = Not much fun
